Answer:
d. vary and change for both males and females from culture to culture
Explanation:
Gender roles vary for both females and males across cultures. This can be observed in the way some societies are patriarchal and some are matriarchal. For example: in many Asian cultures, traditionally males head the families. It's their responsibility to engage in outside work and take important decisions for the family while women take care of household chores. This is reversed in some cultures like that present in Meghalaya, India. Here women are dominant figures in households. They inherit property, give their family name to children and after marriage the man comes to live with the woman's family. Hence gender roles are variable culture to culture.
Biological or "Darwinian" fitness is being able to live long enough to reproduce and keep the population or species alive.
<h3><u>Benefits of smooth stem over rough stem:</u></h3>
Smooth stem plants like guava, eucalyptus etc do have a smooth layer of bark over its stem that comes out as a skin when they shed their barks. Whereas most of the other plants like mango, banyan etc do have a rough corrugated layer of bark over their stem.
The smooth stem doesn’t let water to accumulate in the bark which can led to infections to the tree. It also doesn’t allow any seed to settle on bark that can led to growth of parasites. Thereby this smooth bark saves the trees from some of the probable harm to the tree.
Answer:
a fuel for cellular respiration and a starting material for making other organic molecules.
Explanation:
Plants have the ability to produce sugars by the process of photosynthesis. Plants can convert the inorganic CO2 from the air into the organic nutrients such as sugars. Plants store sugars so that they can serve as a source of ATP for the cells as and when required. The sugars enter the process of cellular respiration and are oxidized into CO2 and H2O. In addition, the energy of chemical bonds of the sugars is used to form ATP molecules.
Plants also use sugars to synthesize other organic molecules. For example, several intermediates of Kreb's cycle can serve as precursors for the synthesis of amino acids. Amino acids are joined together to form different proteins.
